Professor Lampe is using gamification in his 200-student lecture classes to make them more interesting. He says big-class lectures can often be as boring for the professor as they are for the students. A little bit of game-type action can spice things up and make classes more interesting. Near the end of the video he points out that gamification is becoming popular for employee training in private enterprise, so why not use the concept in universities and other educational institutions?

Frequent contributor Bennett Haselton writes this week with his favorite novelty science gift items for 2012. Levitation engines, puzzles, optical illusions brought to life, and all of the tips and tricks he's found for getting the products to work correctly. Decorative, whimsical, and not too expensive — except for the items that have earned it by being pretty amazing. Read on for the details, and be sure to mention other good possibilities (Just 14 shopping days left until Christmas) in the comments below.
A couple of weeks ago you had a chance to ask Canonical Ltd. and the Ubuntu Foundation founder, Mark Shuttleworth, anything about software and vacationing in space. Below you'll find his answers to your questions. Make sure to look for our live discussion tomorrow with free software advocate and CTO of Rhombus Tech, Luke Leighton. The interview will start at 1:30 EST.
Nikola Tesla, and has been collecting antique electric devices of a particular kind: ones that send electricity through the human body to effect medical benefits, many of which do so with the aid of Tesla coils. Tesla's not the only inventor involved, of course, but his influence overlapped and widely influenced the golden age of electrotherapy. Behary's day job as a machinist means he has the skills to rehabilitate and restore these aging beasts, too, along with a growing family of related devices. He's assembled them now, in West Palm Beach, Florida, into the Turn of the Century Electrotherapy Museum. This is a museum of my favorite kind: home-based and intimate, but with serious depth. Though it's open only by appointment, arranging a visit there is worth it, whether you're otherwise part of the Tesla community or not. Behary knows his collection inside and out, with the kind of deep knowledge it takes to fabricate replacement parts and revamp the internal wiring. The devices themselves are accessible, with original and restored pieces up close and personal — you need to be mindful about which ones are humming and crackling at any given moment. (There's also an archive with books, papers, and other effects relating to Tesla and other electric pioneers, not to mention glowing tubes that predate the modern vacuum tube, and the oldest known surviving Tesla coils, recovered from beneath their maker's Boston mansion. Electrotherapy is the organizing principle, but not the extent of this assembly.) And while Behary isn't fooled by all the therapeutic claims made by some machines' makers about running current through your limbs or around your body, he also doesn't discount them all, either, and points out that some of them really do affect the body as claimed. Yes, he's tried most of the machines himself, though he admits he's never dared taking the juice of his personal Tesla-powered electric chair. View the first video for a tour of part of this astounding collection; the second video is an interview with Jeff Behary.
whole bunch of Android VNC apps out there already? And plenty for iOS, too? You're right. But Cliff says Splashtop is better than the others. It can play video at a full 30 frames per second, and has low enough latency (depending on your connection) that you can play video games remotely in between taking care of that list of server issues your boss emailed to you. Or perhaps, in between work tasks, you take a dip in the ocean, because you're working from the beach, not from a stuffy office. It seems that work and living locations get a little more remote from each other every year, and Splashtop is helping to make that happen. This video interview is, itself, an example of how our world has gotten flatter; Cliff was in China and I was in Florida. The connection wasn't perfect, but the fact that we could have this conversation at all is a wonder. Please note, too, that while Cliff Miller is now Chief Marketing Officer for Splashtop, he was also the founder and first CEO of TurboLinux, so he is not new to Linux. And Splashtop is the company that supplied the "instant on" Linux OS a lot of computer manufacturers bundled with their Windows computers for a few years. Now, of course, they're focusing on the remote desktop, and seem to be making a go of it despite heavy competition in that market niche.
Slashdot regular contributor Bennett Haselton writes "My last article on prediction markets contained an erroneous assumption, one whose implications are far-reaching enough that they deserve their own article. (And if you read to the end, I'm offering $100 to be split between the readers who submit the best alternative solution or the best counter-argument to the points made here.)" Read below for the rest of Bennett's thoughts.
Jon Brodkin writes "The Wii U has been out for two weeks, with most of the attention naturally focusing on the console’s tablet-y GamePad and blockbuster titles such as New Super Mario Bros. U and Assassin’s Creed 3. But $60 games aren’t the only draw on Nintendo’s new system. There are exactly five games on the Nintendo eShop for $20 or less: Nano Assault Neo, Little Inferno, Mighty Switch Force! Hyper Drive Edition, Chasing Aurora, and Trine 2: Director’s Cut. You could call most or all of these indie games, depending on your definition of an independent developer." Read below for the rest of Jon's review.
Eugene Kaspersky probably hates malware just as much as you do on his own machines, but as the head of Kaspersky Labs, the world's largest privately held security software company, he might have a different perspective — the existence of malware and other forms of online malice drives the need for security software of all kinds, and not just on personal desktops or typical internet servers. The SCADA software vulnerabilities of the last few years have led him to announce work on an operating system for industrial control systems of the kind affected by Flame and Stuxnet. But Kaspersky is not just toiling away in the computer equivalent of the CDC: He's been outspoken in his opinions — some of which have drawn ire on Slashdot, like calling for mandatory "Internet ID" and an "Internet Interpol". He's also come out in favor of Internet voting, and against SOPA, even pulling his company out of the BSA over it. More recently, he's been criticized for ties to the current Russian government. (With regard to that Wired article, though, read Kaspersky's detailed response to its claims.) Now, he's agreed to answer Slashdot readers' questions. As usual, you're encouraged to ask all the question you'd like, but please confine your questions to one per post. We'll pass on the best of these for Kaspersky's answers. Update: 12/04 14:20 GMT by T : For more on Kaspersky's thoughts on the importance of online IDs, see this detailed blog posting.
Linux Magazine column for many years and now writes for ZDNet. The ZDNet blurb describes him as "a technologist with over two decades of experience integrating large heterogeneous multi-vendor computing environments in Fortune 500 companies." Most recently, he worked for IBM, and for Unisys before that. So Jason knows plenty about Linux and its role in big-time enterprise computing. In this video, he talks about how Linux needs to take another step forward to gain even more enterprise traction in coming years.
Richard Stallman (RMS) founded the GNU Project in 1984, the Free Software Foundation in 1985, and remains one of the most important and outspoken advocates for software freedom. RMS now spends much of his time fighting excessive extension of copyright laws, digital rights management, and software patents. He's agreed to answer your questions about GNU/Linux, free software, and anything else you like, but please limit yourself to one question per post.
Gaurav Kuchhal (Head of Product, Slashdot) writes "Slashdot Mobile has finally made it out of the gates for tablets as well as phones. The Mobile site for phones launched some weeks back, but now you can take advantage of the changes we've made to read Slashdot easier to read through touch-screen devices on tablets as well as phones. That includes features we've folded in to the mobile version from the desktop-browser view of the site, so you can scan user profiles, sip from the Firehose, and keep up with notifications. See this blog post for more details, and keep the feedback coming. If you see a problem, please tell us about it!"
In addition to founding Canonical Ltd., the Ubuntu Foundation, and funding the Freedom Toaster, Mark Shuttleworth is a space enthusiast. In April 2002 Mark became the second self-funded space tourist and the first African in space. He spent eight days participating in experiments on the International Space Station as part of his $20 million trip. Now he's ready to answer your questions. Ask him anything you like, but please limit yourself to one question per post.
33 Flatbush Ave. in the Brooklyn borough of what David Letterman calls "the world's greatest city." You go to the 7th floor. Congratulations. You have found New York City's community biolab, Genspace. It's a well-equipped facility without a single mad scientist in sight. Indeed, everyone here seems as happy as the people you see in a makerspace -- which should not be surprising, since Genspace is essentially a makerspace for biologists. It is confined to non-hazardous experiments, but there is plenty going on, including ongoing projects and courses with titles like DIY Neuroscience: Controlling Behavior from the Inside. You can keep up with Genspace by following their blog. And of course, if you're in the neighborhood you should stop in. It's a welcoming environment, dedicated to the idea that science is for everyone, not just a chosen few.
Bennett Haselton writes: "Online political futures betting is in a legal limbo in the United States. But with the lifting of legal sanctions, and with the addition of one simple new feature, online futures betting could not only provide more accurate forecasts of the merits of different candidates, but also provide a tool for quieting partisan blowhards who think the opposing party's candidate is going to drag the country to hell. Let the blowhards bet!" You'll find the rest of Bennett's story below.
